COMBINED COMB AND SHIELD.

SPECIFICATION forming part of Letters Patent No. 226,374, dated April 6, 1880.

Application filed November 25, 1879.

To all whom it may concern:

Be it known that I, JAMES S. UP'roN, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain .new and useful Improvements in Combined Cylinder Comb and Shield Applicable to Grain- Separators, 850.; and I do hereby declare that the following is a full, clear, and exact descripion thereof, reference being had to the aceompanying drawings, and to the letters of eference marked thereon, making a part of this specification.

My invention relates to grain-separators; .nd it consistsin the construction and arrangerent of a combined comb and shield for takw.ag the straw from the teeth of the cylinder,

'nd also protecting the cylinder from the straw oein g thrown back upon it from the separator, as will be hereinafter more fully set forth.

In the annexed drawings, Figure 1 is a perspective view of my invention. Figs. 2 and 3 are detailed views, showing the construction of the comb.

A represents part of the frame of a grainseparator, and B is the usual toothed cylinder employed therein, said cylinder having suitable journal-bearin gs and revolved in any of the known and usual ways.

At the back or rear of the cylinder B in he frame is placed the combined comb and shield, constructed in the following manner: 0 is a cast-iron bar extending across the frame A and fastened thereto in any suitable manner. This bar is on the front side formed with two longitudinal flanges, a and b. The upper flange, a, is wider than the lower flange, b, and has in its outer or front edge a series of notches at equal distances apart, in which fit the upper ends of the teeth D D, as shown in Fig. 2. These teeth are made of wrought-iron, and rest in notches made in the flange b, and are there held in place by means of a wroughtiron bar, F, fastened to the bar 0 by bolts 0.

Great difficulty is experienced by parties using thrashers by straw winding around it and retarding the motion of the cylinder. My combined comb and shield entirely prevents this, and at the same time protects the cylinder from the straw being thrown back upon it from the separator.

The peculiar construction, as shown and described, admits of any one or more of the teeth being easily removed in case of breakage and others put in.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

In agrain-separator or similar machine, the combination, with the spiked cylinder B, of the combined comb and shield, consisting of the back bar, 0, provided with the notched flanges a b, the teeth D, and fastening-bar F, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day of November, 1879.

JAMES S. UPTON.
